No. 574,333 3 Claims. (Cl. 5258) ABSTRACT OF THE DISCLOSURE An improved anchorage device for guy wires in which there is provided a substantially flat flashing plate arranged in off-set relation to a means for ready attachment to a sloping shingle roof with the off-set flat flashing plate having a sealing relation to the attachment means, and including a portion thereof adapted to be slipped between overlaying shingles so that, as the attachment means is inserted through a puncture is a roofing shingle, the flashing plate may be drawn down tightly in a contiguous relation to the roofing shingle to prevent leakage of water through the shingle at the puncture through which the attachment means has been inserted.

This invention relates to an improved guy wire anchorage device for attachment to a sloping shingle roof, and more particularly, to a novel roof anchor having an offset disc-like shield or flashing plate so arranged that a portion thereof may be slipped under a roofing shingle without need for removal of the shingle.

An object of the present invention is to provide a simple anchorage device for guy wires of, for example, a radio or television antenna, or display sign, and including means for ready attachment to a shingle roof together with a novel flashing shield uniquely arranged on the attachment means so as to seal the roof from leakage at the point of insertion of the attachment means into the shingle roof.

Heretofore, the conventional guy wire mount related to a lag screw eye or hook device having a wood screw type of thread on its shank portion to be inserted into a shingle roof smeared with a roof cement where the screw punctured the roof surface. With such a device, high winds often caused the antenna to shake the guy wires, working the hook back and forth so as to enlarge the puncture in the roof, causing cracks in the roof cement. Such taut hook mountings are prone to cause eventual leaks in the roof.

An object of the present invention is to provide a secure and water tight attachment, including a novel flashing plate, which is unique in that a portion thereof may be installed under the edge of a shingle, while an attachment shaft is fastened through the shingle roof so as to prevent a leakage in the roof at the puncture formed by the threaded shaft.

Another object of the invention is to provide a novel guy wire anchorage device, including a shaft having aflixed thereto intermediate opposite end portions thereof, an offcentered flashing plate, a lower end portion of the shaft having threads thereon for insertion into and through a roofing shingle, and the opposite or upper end portion of the shaft having threads thereon for receiving a fastening nut and an arcuate arm, the arm having a threaded nut portion adjacent one end for threadingly receiving the threaded end portion of the shaft, another aperture being provided in the arcuate arm adjacent the free opposite outer end thereof in which a guy wire may be attached, and the off-centered flashing plate being so arranged that, as the threaded end portion of the shaft is inserted into and through the roofing shingle, the flashing plate is drawn downwardly toward the roofing shingle until the off-centered flashing plate is contiguous to the last mentioned shingle, the peripheral edge portion of the off-centered 3,408,780 Patented Nov. 5, 1968 flashing plate, having the greatest length, is wedged between the first mentioned contiguous roofing shingle and a next immediately above shingle so that the flashing plate serves to prevent leakage of water about the screw threads of the lower end portion of the shaft inserted into and through such roofing shingle.

These and other objects and features of the invention are pointed out in the following description in terms of the embodiment thereof, which is shown in the accompanying drawings wherein like numerals indicate like parts. It is to be understood, however, that the drawings are for the purpose of illustration only and are not defined as a definition of the limits of the invention, reference being had to the appended claims for this purpose.

FIGURE 8 is a vertical view of the modified anchorage device shown in FIGURE 6 with the flashing plate being shown in section; and

FIGURE 9 shows a fragmentary section of the sheathing and supporting rafters of the shingled roof of FIG- URE 7, and portrays the manner in which a portion of the rectangular flashing plate of the anchorage device of FIGURE 7 is wedged between the next immediate above shingle and the contiguous shingle in which the shaft of the anchorage device passes for being threadingly bolted to the underside of a wooden supporting roof rafter.

Referring now to the drawings and particularly to FIGURES 1 to 5 thereof, the anchorage device includes a shaft .10, having a substantially flat circular flashing plate or shield 12 mounted in an eccentric or off-centered relation with the shaft 10 and formed integrally with or aflixed or fused to and about the shaft 10 in sealing relation therewith at 14 intermediate opposite end portions 16 and 18 of the shaft 10.

The end portion 16 of the shaft has suitable machine threads 20 formed therein and arranged to be threadedly engaged by a correspondingly threaded fastening nut 22 and by a threaded nut portion 24 formed integrally with one end of an arcuate arm 26.

The arcuate arm 26 has an aperture 28 therein adjacent its outer free end. A guy wire 30, as shown in FIGURE 5, may be inserted in the aperture 28 and fastened to the arcuate arm 26, which may be threadedly engaged by the nut portion 24 on the machine threads 20 and locked in an adjusted position thereon by suitable screw threaded adjustments of the fastening nut 22 into an abutting relation with the nut portion 24 of the arcuate arm 26.

The opposite end portion 18 of the shaft 10 is tapered and has a wood screw type of thread 32 thereon for screw threaded engagement to the sheathing 31 and sup porting roof rafters 33 of a building to mount the guy wire anchorage device 10.

Operation The guy wire anchorage devices 10 and 40 ofthe present inventionmay be used to anchor any suitable device to the sheathing 31 and supporting roof rafters 33 of a shingle roof or sidewalls of a building, without the danger of leaksarising through the mounting thereof, so as to provide an excellent anchorage means for a radio or television antenna guy wire or a display sign attachment. It will be obvious that, while the circular flashing plate device 10 is designed to be screw threaded into the sheathing 31 and supporting roof rafters 33 and the rectangular flashing plate device 40 is designed to be bolted through the sheathing 31 and supporting roof rafters 33, these means of fastening may be made interchangeable on the devices 10 and 40, without departing from the scope of the invention.

Referring now to FIGURES 1 to 5, it will be apparent that the proper placement of the tapered screw threaded end portion 18 of the shaft 10 in relation to the shingle butt of the immediately above shingle is necessary to insure weather tightness. A guide hole in a shingle 35 as shown in FIGURES 3 and 5, in which the tapered end portion 18 is to be inserted should be positioned from the butt of the immediately above shingle 39 a distance equal to the shortest radius of the peripheral edge of the circular flashing plate 12 from the shaft 10. The guide hole should be further placed in the lower shingle 35 at a point free of cracks or joints that might cause leakage, and also so as to avoid cracks or joints in the upper shingle 39.

Thus, in an anchorage device having the measurements given on FIGURES 1 and 2, it will be seen that the shaft 10 is positioned in an off-center relation in the flashing plate 12 with the shortest of the peripheral edge of the plate 12 from the shaft 10 being one inch and the greatest radius of the peripheral edge of the plate 12 from the shaft 10 being two inches. In mounting such an anchorage device, the guide hole for the tapered end portion 18 of the shaft 10 may be placed in the shingle 35 approximately one inch from the butt 37 of the upper shingle 39. Then, upon the tapered end portion 18 of the shaft 10 being inserted in such guide hole, the circular flashing plate 12 may be drawn into a contiguous relation with the lower shingle 35, by the screw threaded tapered end portion 18 of the shaft 10 being screwed into the shingle 35 by hand or by the use of a tool, until the position shown by FIGURE 3 is reached. In this position, the butt 37 of the upper shingle 39 would extend tangentially to the peripheral edge of the circular flashing plate 12 having the shortest radius from the shaft 10 (as for example one inch).

A claw end of a hammer or other suitable tool may be used to raise the free end of the upper shingle 39 enough to permit the anchorage device 10 to be threaded fully into the lower shingle 35, while the circular shield or flashing plate 12 passes under the upper shingle 39 as the shield or flashing plate 12 is angularly adjusted from the position shown by FIGURES 4 and 5 in which the portion of the flashing plate 12, having the peripheral edge of greatest radius from the shaft 10 (as for example two inches), will be disposed immediately between the lower shingle 35 andthe-upper shingle 39. The off-center relation of the shaft 10 to the circular flashing plate 12 makes it possible to slip the flashing plate 12 between the lower and upper shingles 35 and 39 without removing the upper shingle 39.

With the anchorage device 10 threadingly tightened down contiguous with the lower shingle 35 and at an angular position in which the shield plate 12, having the peripheral edge of greatest radius from the shaft 10 immediately under the shingle 39, the anchorage device 10 will then be ready for guy wire attachment. In order to provide themaximum strength of mounting, the arcuate arm 26 should be positioned as low as possible on the machine threaded portion 20 of the shaft 10. The guy wire 30, as shown by FIGURE 5, may then be inserted in the aperture 28 in the arm 26 and secured thereto. Obviously, the arm 26 is free to move with the stresses set up in the guy wire 30. 7

With the arm 26 removed, the anchorage device 10 may still provide a weather-proof and a convenient and secure mounting means for display signs or the like.

-In either case, the shield or flashing plate 12 cooperates with the upper shingle 39 to shield the screw hole in which the tapered end portion 18 of the shaft 10 is tightly threaded from the leakage of Water around the tapered portion 18 due to weathering rain, snow and sleet. The flashing plate 12 is unique in that it may be installed on a sloping shingle roof with a portion thereof between an upper shingle 39 and a lower shingle 35 without the need for removing a single shingle.

The offset arrangement of the circular flashing shield 12 on the threaded shaft 10 permits a portion of the shield 12 thus to be slipped under the edge of an upper shingle 39 While being threaded into the sheathing 31 and supporting roof rafters 33 of a lower roof shingle 35 so as to provide a secure anchorage and a weather tight attachment, because of the unique flashing plate 12 being formed integrally with the shaft 10 of the anchorage device.

Referring now to FIGURES 6 to 9 of the drawings, the modified anchorage device includes a shaft 41, having a substantially flat rectangularly shaped flashing plate or shield 42 mounted in an eccentric or off-centered relation with the shaft 41 and formed integrally with or aflixed or fused to and about the shaft 41 in sealing relation therewith at 43 intermediate opposite ends 44 and 46 of said shaft 41. v

The upper end portion 44 of the shaft 41 has suitable machine threads formed therein and arranged to be engaged threadingly by a correspondingly threaded fastening nut portion 24 formed integrally with one end of an arcuate arm 26, which also has an aperture 28 adjacent its free outer end for securing the guy wire 30 thereto. It will be apparent that the arcuate arm in both modifications are identical.

The opposite or lower end 49 of the shaft 41 is not tapered or provided with screw threads, as shown in FIG- URES 1 to 5, but has a straight shank that is provided with machine threads 51. The shank portion 49 of the shaft 41 is adapted to be passed through aligned apertures formed through the roofing shingle 35 and its wooden supporting sheathing 31 and roof rafters 33. The lower end of the threaded shank portion 49 of the shaft 41, which projects through and below the roof rafter 33, is adapted to receive a washer 56 and a machine nut 58. When the machine nut 58 is drawn up tightly against the washer 56 forcing it to engage the underside of the roofing rafter 33, the guy wire anchorage device 40 will be securely fastened to the roofand ready for attachment of its guy wire 30.

It is not believed necessary to further describe in detail the proper placement and positioning of the anchorage device 40 with respect of the roof shingles 35 and 39 since the description given with respect of the anchorage device applies with equal force and effect to the anchorage device 40.

Although only two embodiments of the invention have been illustrated and described, various changes in the form and relative arrangements of the parts, which will now appear to those skilled in the art, may be made without departing from the scope of the invention. Reference is, therefore, to be had to the appended claims for a definition of the limits of the invention.
